Why have I come to italti?

My name is Brian, I come from China. I have learned English for four months. I think I just  I can only speak some simple sentences. I am interested in English. I am not smart but I am diligent. I study English everyday. I like watching American movies and listening to American music. Now I can sing several songs. My favorite song is "All of me". It's a very nice song. Watching movies and listening to music can help my English.I learn pronunciation from songs. I also listen to speeches. Especially Steven Jobs' speeches. He uses a lot of good adjectives words to describe his products. I have learnted many adjective words, Ssuch as beautiful, wonderful, terrific, gorgeous, unbelievable and fantastic. (in English we use a comma [,] to sperate words in a list) 
I want to find a native speaker to help improve my English. Meanwhile I can teach you English also.I can teach you patiently and I hope you can teach me like that.
Thank you for reading. Have a good day.
